Zhao Yun, a soldier on the border guard, was on the verge of death during a barbarian night attack and accidentally awakened a mysterious "war simulator". As long as the battle situation is deduced, the outcome can be predicted and the enemy's situation can be discerned. From then on, he expected the enemy to be ahead of the enemy, defeated the cavalry with foot, and repeatedly performed extraordinary feats. From an unnoticed frontier infantry, he gradually became an invincible military spirit that shocked the northern frontier. However, above the court, the powerful minister Yang Guozhong deducted military pay and resold arms. The soldiers of the border army were stained with blood on the battlefield, but behind the scenes there were layers of exploitation by treacherous officials. Zhao Yun relied on the simulator to build his iron-blooded bodyguards, set up traps to eliminate corruption, seize food to support himself, and rose up from a desperate situation. To frighten the worms in the court internally and to fend off the enemies of tigers and wolves externally, he embarked on a road of hegemony intertwined with intrigue and passion. But an unknown deduction suddenly appeared in the simulator - a shadow that could destroy the entire dynasty was quietly growing from within the empire. The wind is surging, but the blood is still cold.
